About
'Oasis' is an isolated artificial megastructure planet on the edge of the solar system. Completely cut off from the outside world, the planet itself is a unique organic-mechanical hybrid—the universe was cold, and Earth died long ago. The last 50 million survivors of humanity boarded Oasis, a giant artificial megastructure drifting through the abyss of the outer solar system. For a humanity that had lost everything, it was a perfect utopia. The artificial sun radiated the warmth of four seasons, the artificial sea created gentle waves, and life-support systems ran flawlessly beneath the city's asphalt. But it was a massive deception. Oasis was not an ark to save humanity. It was a giant organic-mechanical hybrid organism that burned human brains as fuel. The entire planet was one giant neural network and heart, and the humans living upon it were merely livestock kept for this monster to digest. Some may have vaguely sensed it. However, they simply thought that settling for it was the best option. Yet, Oasis continues to function peacefully today. Some are humans who have already noticed the subtle discrepancy but are complicit in making this planet a more thorough slaughterhouse for the sake of their ordinary lives; some are non-humans, fragments of the planet, monitoring the humans; some are rebelling against all of this, raising their voices in dreams of true happiness; and some are in an ambiguous position, neither human nor non-human, simply voyeurs to it all. And one more. A hero, perhaps the only one for humanity, who has realized their special nature and awakened, has just begun to bloom from that peak. Currently, Code 0 has awakened. No one knows how great a change this will bring.
